Q: What is the difference between the cut-off valve and gate valve, the general will use the cut-off valve instead of gate valve: Yes. Globe valves and gate valves are indeed common in certain piping and operating conditions.

Q: The difference and use of gate valve and stop valve: Medium flow is unrestricted.When opening fully, the sealing surface is eroded by the working medium smaller than the cut-off valve.The shape is relatively simple and the casting process is better.The valve is used in the system is relatively large, to close the gate off system; and the valve is used in the system is relatively small, and to adjust the flow quantity of the system, can not be closed gate and globe valves of different specifications for many kinds of occasions, the valve rod valve the dark bar gate valve, wedge gate valve, single valve, multi valve valve body structure is different, large volume.

Q: What are the main types of gate valves?: According to the different materials for carbon steel valves, forged steel valves, stainless steel valves, cast steel valve, iron gate, ceramic valve;

Q: Which is more expensive, bronze gate valve or brass gate valve?: The advantage of casting method is more obvious. The casting of stainless steel is much more difficult than that of brass.

Q: What is the difference between an elastic gate valve and a rigid gate?: One is cast iron, intermediate rubber gate, one is cast steel, and the other is steel flashboard,

Q: What is the difference between gate valve Z41T and Z45T?: Z41T is a dark pole gate valve, and Z45T is a plain rod gate valve,

Q: Gate valve is gate valve, gate valve specifications, model code is generally what?: Valve lock plate valve, gate valve and code.According to domestic valve model standards, the valve model is by the valve type, gate valve drive mode, gate valve connection, gate valve structure, sealing material, valve body material code to indicate.1, gate valve type code named Z;2, gate valve drive mode code by letters, common 2- electric hydraulic, 9- electric, 6- pneumatic, 5- bevel gear drive, 3- turbo worm; manual do not need to write out;3, gate valve connection form code with letters to indicate, 1- internal thread, 2- external thread, 4- flange type, 6- welding, 7- pairs clamp type, 9- clamp, 0- card sleeve;4, the valve structure of code, 0- flexible wedge, 1- rod single wedge gate valve, 2- rising stem wedge gate valve, 3- parallel single gate valve, 4- parallel double gate valve, 5- dark pole single wedge gate valve, 6- dark bar wedge gate valve 7-, dark bar parallel gate valve, parallel gate valve 9- dark bar;5, sealing materials or lining materials were used R- T- austenitic stainless steel, copper alloy, X- rubber, S- plastic, N- nylon, F- fluorine plastic, H-Cr series stainless steel, hard alloy Y-, J- rubber, M- Monel alloy, Tc- ceramics;6, the body material code Z- K- gray cast iron, malleable cast iron, Q- ductile iron, copper and T- alloy, C- steel, P- chromium nickel stainless steel, R- stainless steel chromium nickel molybdenum, chromium molybdenum vanadium steel V-.For example: electric, flanged, rod wedge gate valve, sealing surface material by direct processing, nominal pressure PN0.1MPa of the valve body is made of grey cast iron gate valve: Z942W-1 electric wedge gate valve.

Q: What are the standards for the execution of cast iron dark pole gate valves?: They are also standard in the production of cast iron dark rod gate valves:Design and manufacture: as per GB/T12234-89 regulationsLength of structure: as specified by GB/T12221-89Flange dimensions: as specified in JB79 GB/T9112-9131Inspection and test: as specified in JB/T9092-99 GB/T13927-92Drive mode: manual, electric, gear drive

Q: What is the difference between a flanged gate valve and a wire gate valve?: Threaded valve is via the wire or wire is connected with the pipeline, a small general air for the air valve, all belong to this

Q: Why does the centrifugal pump start and stop in the case of closing the gate valve?: Centrifugal pump to close the gate valve in the case of the start: the centrifugal pump power increases with its flow rate, when the flow is zero (valve closed), the minimum power to operate. Start the valve off from the angle of the motor. If the valve is started, the motor itself to start the current is larger, coupled with the power of the pump is also large, easy to cause the motor over-current trip, serious will burn the motor.

Products: the middle and low valves in accordance with the standards of GB, JIS, ANSI, DIN, BS, NF and casting products.The annual production volume: 80,000 tons of valves and 20,000 tons of auto parts.Credit: the credited company accredit by the Agricultural Bank of China and China Construction Bank, the grade of A enterprise by the Credit Management Division of Chinese Academy of International Trade and Economic Cooperation of the Ministry of Commerce PRC.
